Major trends in the forecast period include development of intelligent indoor air monitoring solutions, adoption of smart sensor-driven air purifiers, expansion of sustainable filtration and purification technologies, advancement of digitally optimized air quality systems, integration of AI-enhanced indoor air management.

The increasing prevalence of airborne diseases is expected to drive the growth of the indoor air purification market going forward. Airborne diseases are conditions caused by the transmission of viruses, bacteria, or other pathogens through the air in the form of aerosols or droplets over short or long distances. The prevalence of airborne diseases is rising because global urbanization leads to higher population density and increased air-polluting emissions, making enclosed spaces more conducive to pathogen accumulation and spread. Indoor air purification systems help mitigate airborne diseases by continuously filtering and disinfecting indoor air, thereby reducing the concentration of infectious aerosols and improving overall respiratory health in enclosed environments. For example, in March 2024, according to the Centers for Disease Control and Prevention, a US-based government agency, the number of tuberculosis cases increased from 8,320 in 2022 to 9,615 in 2023, reflecting a rise of 1,295 cases. Therefore, the increasing prevalence of airborne diseases is expected to drive the growth of the indoor air purification market.

Major companies operating in the indoor air purification market are focusing on developing innovative solutions, such as IoT-enabled molecular air purification systems, to gain a competitive advantage. An IoT-enabled molecular air purification system integrates advanced filtration at the molecular level - such as photocatalytic oxidation or UV-A/UV-C treatment - with connected sensors and smart controls to dynamically manage indoor air quality. For instance, in September 2024, Havells Studio, an India-based consumer electricals company, launched the Studio Meditate AP400/AP250 air purifiers featuring spacetech photocatalytic oxidation, wireless mobile device charging, and IoT home-ecosystem compatibility with real-time AQI monitoring. This technological advancement improves purification effectiveness and user convenience, although higher unit costs and integration challenges may slow adoption in price-sensitive segments.

In July 2023, MANN+HUMMEL, a Germany-based filtration technology company, acquired Suzhou U-air Environmental Technology Co., Ltd. for an undisclosed amount. This acquisition aims to bolster Mann+Hummel's air filtration capabilities and market presence in China and Southeast Asia by securing a majority stake in Suzhou U-Air Environmental Technology, which will enhance production capacity and allow for quicker responses to customer demands for high-quality air filtration solutions. Suzhou U-air Environmental Technology Co., Ltd. (U-Air) is a China-based company specializing in air filtration products and cleanroom equipment.
